Intermittent hanging after using Web Tools [message #180304]

I've been using Eclipse 3.2 on Debian Linux for a while and it has been
pretty stable. However, I recently starting using Web Tools and the
J2EE perspective, and now Eclipse hangs intermittently. Usually it
hangs when I perform some random action, like opening up help or
commiting a file.

Is this a known problem? If not, is there some way I can debug it to
find out where it is hanging? I can't reproduce it on demand, so I'd
need a way to investigate it after the hang occurs.

Not sure which JRE you use, but I have a vague memory of hearing of
problems with the one that "comes with" Debian Linux. So you might
google and/or try othere JRE's?

Thanks for your reply. I think I solved my problem. I had changed my
JRE to use the J2EE 1.5 one. I changed it back to the standard 1.5 one
from Sun and haven't had a hang since.

I did a kill -3 on one of the hangs. Part of the stack trace follows in
case anybody is interested.
